![]() If we wanted to, weĬould write this as C one H one just like that to You're just saying the ratio, OK, look, it's a ratio of six to six, which is the same thing as one to one. One to one, you get that right over here, it's very easy to go from a molecular formula toĪn empirical formula. Tells us that each benzene molecule has six hydrogens, and, sorry, six carbons and six, (laughs) I'm really having trouble today, six hydrogens, (laughs) six carbons, and, six hydrogens. And the molecular formulaįor benzene, which is now going to give us more information than the empirical formula, That's when you would want to go to the molecular formula. Now you might say, OK, that's nice, I now know that if I'mĭealing with benzene I have one carbon for every hydrogen or one hydrogen for every carbon, but what does, how many ofĮach of these do you actually have in a benzene molecule? To answer that question, One carbon for every, for every hydrogen. So an empirical formula gives you a ratio of the elements in the molecule. ![]() The ratios of the different elements that they had in a molecule. ![]() They could at least come up with, they could observe Weren't able to look at just one molecule, but I'm about to write down the empirical formula, isīecause early chemists, they can't look, they Some observations that make you think this new thing. Know, I from empirical evidence I now believe this, this Is referring to something that comes from observation And you might be thinking, what does empirical mean? In general, the word "empirical" Well, that might be, in that case, it might be useful to move And there's other namingĬonventions that do give more information, but you might say, well, I actually want to know more about the actual particularĮlements that make it up. ![]() Tells you very little about what actually So, for example, you could be referring to a molecule of benzene. This video is think about the different ways to ![]()
